Volume Activation - Windos 2012 R2 and Windows 2008 R2

Hello

I've got a Windows 2012 R2 server (serverA) that I'm successfully using to activate 2012 R2 servers using AD Activation.
I now need to activate 2008 R2 servers.

I was looking to use the same ServerA to also activate 2008 R2 servers through KMS as well as activating 2012 R2 through AD Activation

When I use the Volume Activation Tools to install the 2008 R2 Host key, I get the following :- please see attached screenshot

have found the answer before checking in to see other answers ..

the answer is "yes" .. online AD activation and KMS activation can occur on the same server ..
I was using a downlevel license key which prompted the error

are you using the correct KMS product key?
Windows Server 2008 R2 Web                  6TPJF-RBVHG-WBW2R-86QPH-6RTM4
Windows Server 2008 R2 HPC edition     TT8MH-CG224-D3D7Q-498W2-9QCTX
Windows Server 2008 R2 Standard          YC6KT-GKW9T-YTKYR-T4X34-R7VHC
Windows Server 2008 R2 Enterprise        489J6-VHDMP-X63PK-3K798-CPX3Y
Windows Server 2008 R2 Datacenter       74YFP-3QFB3-KQT8W-PMXWJ-7M648

AFAIK you need to use a lower version server with updates to KMS to activate that version and higher versions. Not sure you can go the other way have higher version activate lower version
